The wide application of aluminum alloy has led to the development of aluminum alloy welding technology. At the same time, the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the research hotspots.

Applications for 4A01

Aluminum silicon alloy is a kind of forging and casting alloy mainly composed of aluminum and silicon. It generally contains 11% silicon. At the same time, a small amount of copper, iron and nickel are added to improve the strength. The density is 2.6-2.7g/cm3. The thermal conductivity is 101-126 w / (m ·℃). Young's modulus is 71.0gpa. 5 J. The fatigue limit is ± 45MPa.

It is used to manufacture low and medium strength castings with complex shape, such as cover plate, motor housing, bracket, etc., and also used as brazing solder. When the silicon content is low (such as 0.7), the ductility of Al Si alloy is better, and it is often used as deformation alloy; When the silicon content is high (e.g. 7%), the Al Si alloy melt has better filling property and is often used as casting alloy. In Al Si alloy with Si content exceeding Al Si eutectic point (Si 12.6%), when the content of Si particles is up to 14.5% ~ 25%, the addition of Ni, Cu, Mg and other elements can improve its comprehensive mechanical properties. They can be used in automobile engines to replace cast iron cylinders and significantly reduce weight. The Al Si alloy used as cylinder can be electrochemically treated to etch the surface aluminum and retain the primary silicon spots embedded in the matrix on the inner wall of the cylinder. The scratch resistance and wear resistance of the alloy can be significantly improved. The alloy with 11% ~ 13% silicon content is one of the best piston materials because of its light weight, low coefficient of expansion and high corrosion resistance. In the Al Si alloy with silicon content more than 11.7% of Al Si eutectic point, silicon particles can significantly improve the wear resistance of the alloy, forming a kind of wear-resistant alloy with wide application. The alloy containing 11% ~ 13% silicon is one of the best piston materials because of its light weight, low coefficient of expansion and high corrosion resistance. The physical properties of aluminum can be changed by adding related non-metallic raw materials
